[0002] With the rapid development of my country's industry, steel production has reached the top of the world, with an average of 300 million tons of steel annually used for welding, accounting for over 50% of the global welding production. However, with the previous generation of experienced welders approaching retirement, the younger generation is reluctant to engage in pure manual welding. Furthermore, high labor costs and welder wages, which are higher than those in other industries (much higher than the average manufacturing wage), place a heavy financial burden on companies.

[0025] See also Figures 1 to 8 As shown, a preferred embodiment of the present invention discloses an automated welding apparatus 100 for welding a workpiece. The automated welding apparatus 100 is primarily designed for welding longitudinal circumferential seams on workpieces, including butt welds, fillet welds, and other weld types. The automated welding apparatus 100 not only meets the need for quick and convenient welding posture adjustment, but also allows workers to intuitively manually adjust the welding torch position during the welding process to ensure weld quality.

[0026] The automated welding equipment 100 includes a support mechanism 10, a vertically extending arc-length tracking carriage 20, a welding gun actuator 30 connected to the arc-length tracking carriage 20, and a posture adjustment mechanism 50 connected between the arc-length tracking carriage 20 and the support mechanism 10. The posture adjustment mechanism 50 is used to adjust the relative position of the arc-length tracking carriage 20 on the support mechanism 10.

[0027] See also Figure 2 As shown, the support mechanism 10 comprises a fixed base 11 fixed to the ground or a reference surface, a column 12 extending vertically from the fixed base 11, a longitudinally extending crossbeam 13, and a motion mechanism 40 connected between the column 12 and the crossbeam 13. In other words, the column 12 and the crossbeam 13 are arranged perpendicular to each other. In this embodiment, the motion mechanism 40 is used to adjust the longitudinal and vertical position of the crossbeam 13 relative to the fixed base 11 and the column 12, and to clamp and fix the crossbeam 13.

[0028] Specifically, the motion mechanism 40 is provided with a column clamping portion 41 at one end and a beam clamping portion 42 at the other end, the column clamping portion 41 and the beam clamping portion 42 being arranged perpendicular to each other. The column clamping portion 41 is provided with a receiving slot that vertically penetrates and clamps the outer periphery of the column 12, so that the column clamping portion 41 is connected to the column 12 and adjusts the vertical position of the motion mechanism 40, to which the beam 13 is connected, relative to the fixed base 11 and the column 12. At the same time, the column clamping portion 41 controls the motion mechanism 40's clamping, fixing, and releasing of the column 12 through a wrench on the column clamping portion 41. The beam clamping portion 42 is provided with a receiving groove that penetrates longitudinally and is clamped on the outer periphery of the beam 13, so that the beam clamping portion 42 is connected to the beam 13 and adjusts the position of the beam 13 relative to the column 12 in the longitudinal direction; at the same time, the beam clamping portion 42 controls the movement mechanism 40 to clamp, fix and release the beam 13 through the wrench thereon.

[0029] See also Figures 6 to 8As shown, the arc length tracking carriage 20 can achieve stable and reliable automatic arc length tracking during TIG welding. The arc length tracking carriage 20 includes a vertically extending housing 21, a motor 22 located above the housing 21, and a slider 23 and a lead screw 24 housed within the housing 21. The housing 21 is provided with a receiving slot (not numbered) extending vertically therethrough. The motor 22 is a servo motor and is fixed above the housing 11, with its motor shaft extending into the receiving slot.

[0030] The slider 23 is circumferentially fixed within the receiving groove and extends downwardly out of the housing 21. The welding gun actuator 30 is connected below the slider 23. Specifically, the housing 21 and the slider 23 are provided with a protrusion located on one of the inner wall of the housing 21 or the outer circumference of the slider 23, and a recess located on the other of the inner wall of the housing 21 or the outer circumference of the slider 23. The protrusion and recess cooperate to secure the slider 23 circumferentially within the housing 21.

[0031] The screw rod 24 extends vertically and has its upper end connected and fixed to the motor shaft of the motor 22. The motor 22 drives the screw rod 24 to rotate via the motor shaft. The slider 23 has a blind hole that is recessed vertically downward from its top end and an internal thread formed on the inner wall of the blind hole. The screw rod 24 is at least partially received in the blind hole and has an external thread formed on its outer circumference. The external thread of the screw rod 24 is connected to the internal thread of the slider 23, thereby threading the screw rod 24 and the slider 23 together.

[0032] The motor 22 drives the screw 24 to rotate, driving the slider 23 vertically, which in turn drives the welding gun actuator 30 to move vertically relative to the workpiece. For applications with small spacing and frequent angle changes, the arc-length tracking carriage 20 automatically adjusts the arc length, thereby completing TIG automatic welding of the entire workpiece. The welding gun actuator 30 comprises a support rod 31 connected to the bottom of the slider 23, a welding gun holder 32 adjustable relative to the support rod 31, and a welding gun 33 mounted on the welding gun holder 32.

In this embodiment, the slider 23 has a speed accuracy of 1%, the controller's voltage tracking accuracy is ±0.1V, and the slider 23's vertical motion accuracy is 0.1mm. This enables the arc-length tracking carriage 20 to exhibit high arc-length sensitivity, timely tracking, smooth operation, and reliable stability. Furthermore, because the arc-length tracking carriage 20's housing 21 utilizes a cylindrical structure, its overall volume is half that of conventional arc-length carriages.

Furthermore, a wrench on the second clamping portion 72 controls the second clamping mechanism 70's clamping and release of the second shaft 52.

[0038] The second shaft 52 is provided with a second fine-tuning knob 520 at one axial end. The second fine-tuning knob 520 is used to fine-tune the longitudinal position of the third clamping mechanism 80 relative to the second clamping mechanism 70. The third clamping mechanism 80 is provided with a third connecting portion 81 at one lateral end and a third clamping portion 82 at the other lateral end. The third connecting portion 81 is fixedly connected to the other axial end of the second shaft 52.
